Title: A grid apparatus for a color cathode ray tube which eliminates vibration of the grids
Inventor: KUME HISAO
IPC: H01J31/20
Filed: 1990-04-12
Granted: 2001-07-10
Abstract: A grid apparatus which has a multiplicity of ribbon-shaped grid elements stretched in tension and attached to a frame which comprises a pair of support bars and a pair of resilient support members. Metallic members which have a larger thermal expansion coefficient than the resilient support members are connected to the reverse surfaces of the resilient support members opposite the side to which the grid-elements are attached. In the grid apparatus during heat treatment, thermal creep of the grid elements is prevented so that the tension of the grid elements will remain high when the normal temperature state is resumed.      A method of making such grid apparatus includes an additional heat treatment such as a blackening process after the reduction of the tension applied to the grid elements by the resilient support members and the support bars, hence preventing thermal creep of the grid elements to produce a high-reliability with high tension of the grid elements.

Title: Waste container lid system
Inventor: HORPESTAD MELVIN V
IPC: B65F1/16
Filed: 1991-03-19
Granted: 1995-05-09
Abstract: Existing dumpster lids are difficult for a user to lift and also leak some water into the container. The lids also tend to become bent when dumping into a full garbage truck,  as the lid presses against the mound of trash. The present invention provides a waste container and lid assembly comprising a lid having a pivot arm which operates on a pivoting surface attached to the side of the container and having a fulcrum. The pivot arm has first, second and third pivot points on its lower surface in order to move the pivot point as the centre of gravity of the lid shifts during opening to keep the centre of gravity ap-proximately over the pivot point. The lid is connected to the container by a two-piece hinge which swings the pivot arm clear of the supporting plates when the container is inverted. This alows the lid to swing freely on the two-part hinge which also permits the lid to move up or down while hanging in order to avoid damage to the lid if a solid mass is struck. The lid when closed is also able to slide forward to permit automatic unlocking.

Title: Repressors of the trans-activating function of papillomavirus e2 proteins
Inventor: ANDROPHY ELLIOT J
IPC: C12R1/85
Filed: 1992-01-28
Granted: 2000-08-01
Abstract: This invention relates to E2 trans-activation repressors which interfere with normal functioning of the native full-length E2 transcriptional activation protein of the papillomavirus: Native full-length E2 trans-activation protein activates transcription of papillomavirus only through binding to DNA, and it binds to DNA only in the form of a pre-formed homodimer -- a pair of identical polypeptide subunits held together by non-covalent interactions. The E2 trans-activation repressors of this invention are proteins, polypeptides or other molecules that dimerize with full-length native E2 polypeptides to form inactive heterodimers, thus interfering with the formation of active homodimers comprising full-length native E2 polypeptides, thereby repressing papillomavirus transcription and replication. The E2 traps-activation repressors of this invention are advantageously used in the treatment of papillomavirus-infections and their associated diseases.
